I have a few setting like the database-connection that differ between my test- and live-system. Has Visual Studio a feature that determines automatically which settings to use by just pulling one switch somewhere? I don't want to use #if DEBUG because i still want to be able to debug my live-system before i publish it. Is there no better way then just to use a bool?

    What about using a configuration file that you can swap? – PMF Jun 23 '23 at 13:47

  • @HereticMonkey my question was just if there's a build in feature of VS that makes switching between variables before build easy. that would be the recommended way, no? if not, i'm just gonna use a const bool – cattle81194 Jun 26 '23 at 09:17

The best way to make changes based on environment is using environment variables For example you can put a variable name “environmentName” and put its value as develop,prod,stage or any other

Then you can pull it and preform different actions based on it

String env = Environment.GetEnvironmentVariable("environmentName");

Id recommend environment variables from personal experience.
